Photon triplet generation
There are three basic mechanism for photon upconversion in inorganic materials and at least two distinct mechanisms in organic materials. In inorganic materials photon upconversion occurs through energy transfer upconversion (ETU), excited-state absorption (ESA) and photon avalanche (PA). Such processes can be observed in materials with very different sizes and structures, including optical fibers, bulk crystals or nanoparticles, as long as they contain any of the active i… WebMar 26, 2024 · Huang, L. et al.
